MACHINE FOR MIX|N G PLASTER-OF-PARIS.

SPECIFICATION forming part of Letters Patent 0. 688,363, dated December1 1901- Application filed. December 17,1900. Serial No. 40,198. (Nomodel.)

a machine that willfeed, sieve, and mix the,

plaster-of-paris automatically.

Another object of this invention is to so construct the machine that itmay be easily and quickly taken apart or put together, the arrangementbeing simple, inexpensive, unique, and durable and one adapted toefficiently perform all of its intended functions.

With these objects in view and such others as may hereinafter appearmyinvention con-.

sists in the particular construction of the various parts and in thenovel manner of combination and arrangement of the said parts, all ofwhich will bedescribed hereinafter and fully pointed out in the claims.

In the drawings forminga part of this specificat'ion, Figure l is aperspective view of my invention. Fig. 2 is a vertical sectional view.

Referring by letters to the drawings, A rep resents the hopper, whichconsists of a cylindrical receptacle having a cover or top 13 and afunnel-shaped bottom 0. This receptacle isadapted to be secured to thewall or workbench in a vertical position and is provided with a shaft D,journaled in a horizontal p'osition just above the funnel-shaped bottom.The shaft is provided with a semicircular wire frame E and adapted to beoperated by a crank and handle F, the object of which will behereinafter explained. Detachably secured to the funnel-shaped portionof the receptacle is acylindrical section G, secured in the upper end ofwhich is a semicircular sieve H and a deflector I, which is secureddiagonally within the cylinder. J ournaled in the wall of thecylindrical section immediately above the sieve is a shaft J, providedwith a semicircular wire frame K, which rotates in the semicircularsieve and is driven the mixing-blade.

bya pinion L,-mounted upon end of the shaft J, which pinion is adaptedto be thrown into and out of gear by the lock-lever M. The pinion Lengages the pinion N, mounted in the slot upon the upper end of thevertical shaft 0, which shaft is mounted upon the walls of thecylindrical section and is provided upon its lower end with amixing-blade P, consisting of a steel band bent pear-shaped. The shaft 0is provided with a fixed pinion Q, which engages and is driven by abeveled gear-wheel R, provided with a handle S.

It will be readily seen that by placing the plasterbf-paris in thereceptacle it may be easilytransferred to the sieve by turning thehandle F. After a sufficient amount of the material has been transferredto the sieve it maybe forced through by pushing the locklever d0wn,.andthereby connecting or throwing in gear the movable pinion with thepinion mounted upon the shaft carrying the semicircular wire frame whichis adapted to rotate in the'sieve. The wire frame may be thrown out ofgear by pushing the lock-lever up.

The material which passes through the sieve is deflected so as to comefrom the machine on the side at that portion of the wall nearest Themixing-blade is secured to the end of a vertical shaft which is providedwith a movable pinion herein referred to and a fixed or immovable pinionwhich engages and is driven by a beveled gear-wheel having a handlethereon.

Having thus described my invention, What I claim as ,new and useful, anddesire to se= cure by Letters Patent, is-

1. In a machine of the character described, the combination with ahopper; of a cylindrical section thereto, a sieve therein, a revolubleframe in the sieve, a shaft thereto, a vertical shaft upon the wall ofthe cylindrical section, a mixing-blade extending therefrom and meansfor imparting motion to the shaft of the frame from the mixer-shaft.

2. In a machine for mixing plaster-of-paris,

the combination with a hopper; of a cylindrical section, a verticalshaft mounted upon the wall thereof, a mixerblade extending from theshaft, a fixed pinion upon said shaft, a pinion feathered upon theshaft, abeveled gear-Wheel engaging the fixed pinion, a lever forshifting the movable or feathered pinion,

' eled gear-wheel engaging the immovable pin ion, a lever for shiftingthe movable pinion, a beveled gear-wheel adapted to engage the movablepinion, a shaft to said wheel, a, frame thereupon, a concavo-convexsieve secured within the cylindrical section, and a deflector in saidsection, said frame being revoluble in the sieve.
